I'd like to discuss VME boards here. VME based systems are highly modular and was introduced early 80ies as a standardized continuation of Versabus. At first only 68000 family was supported but over the years many CPU types and i/o boards were adapted and the latest standard even support 64bits aka VME64. I intend to contribute drivers for a few early ones suitable for emulation. If you sit on information or ROMs fitting this description please let me know.

I'll take a look at the Besta and see if I can merge the two drivers, I didn't know this, thanks for the pointer!

Edit: Yes, Besta seems to follow the address map and specs of the SYS68K/CPU-30 series launched in Q2/1988, I am only puzzled by the SDRAM which sits in the User EPROM area instead of in the designated SRAM area. I believe that Besta should be a clone if there was a CPU-30 driver.

This is an advanced 68010 based SBC for VME based industrial applications relesed around 1985. Theintended use is in a VME cage together with VME compatible I/O cards and specifically Heurikon own series. Thismanual for Herikon UNIX gives a detailed view on a industrial UNIX configuration:
